I think I speak for many of us who read this forum when I thank you for your informed and well-written input to this forum. Your response to my question about the necessity of breaking in a pre-pro is a case in point. Perhaps you might consider a career change from HVAC to one of the magazines that review this equipment? I look forward to your review of the new Outlaw bookshelf speaker systems, perhaps they will send you a pair to demo?
Many thanks and my goodwill, Dog_Lover (Craig)
